web applications - Download ASPX page with R -


there number of detailed answers on cover authenticated login aspx site , download it. complete n00b haven't been able find simple explanation of how data web form

the following mwe intended example only. , question more intended teach me how wider collection of webpages.

website :

http://data.un.org/data.aspx?d=sna&f=group_code%3a101

what tried , (obviously) failed.

test=read.csv('http://data.un.org/handlers/downloadhandler.ashx?datafilter=group_code:101;country_code:826&datamartid=sna&format=csv&c=2,3,4,6,7,8,9,10,11,12,13&s=_cr_engnameorderby:asc,fiscal_year:desc,_grit_code:asc')

giving me goobledegook view(test)

anything steps me through or points me in right direction gratefully received.

the url accessing using read.csv returning zipped file. download using httr , write contents temp file:

 library(httr)  urlun <- "http://data.un.org/handlers/downloadhandler.ashx?datafilter=group_code:101;country_code:826&datamartid=sna&format=csv&c=2,3,4,6,7,8,9,10,11,12,13&s=_cr_engnameorderby:asc,fiscal_year:desc,_grit_code:asc"  response <- get(urlun)  writebin(content(response, = "raw"), "temp/temp.zip")  fname <- unzip("temp/temp.zip", list = true)$name  unzip("temp/temp.zip", exdir = "temp")  read.csv(paste0("temp/", fname))

alternatively hmisc has useful getzip function:

 library(hmisc)  urlun <- "http://data.un.org/handlers/downloadhandler.ashx?datafilter=group_code:101;country_code:826&datamartid=sna&format=csv&c=2,3,4,6,7,8,9,10,11,12,13&s=_cr_engnameorderby:asc,fiscal_year:desc,_grit_code:asc"  undata <- read.csv(getzip(urlun))
